Video: Going to space is definitely one of the coolest things a human could ever do, but damn if it doesn't do a doozy to your body. If you were able to spend time in space, your bones would become brittle, your leg and back muscles would wither away, the back of your eyeballs might flatten and your heart could lose mass and become more spherical. None of that is good.

Video: Sometimes failure isn't always a bad thing. This 5.79m tall domino tower was only 10 layers away from officially becoming the second tallest in the world — but then gravity claimed yet another victim. As heartbreaking it is to see all this hard work go to waste, it's also pretty cool to watch 241 layers of dominoes, some 3242 in total, come spectacularly crashing to the ground.
Yes, we can. We can totally create the artificial gravity seen in movies like 2001: A Space Odyssey or Elysium, it will just cost a lot of freaking money and require a lot of freaking resources. Real Engineering explains how centrifugal force works as artificial gravity and estimates (using maths cribbed from how much the ISS costs) the cost needed to build it: only around five trillion dollars and 10 years of the world's total aluminium production. And that's just for starters.
Forgive me, but I think it's plausible that these two guys are actually the first mutants in the world, because the way they move so easily around this Chinese pole makes it seem like they have magnetic superpowers or access to an invisible wall. They can flip, slide, stop, walk on nothing, and do things I can't even do on solid ground, all while mid-air on the pole. I can't imagine that they're just human like me and are just simply stronger from lots of practice and hard work. That can't be.
Video: Watch as these diabolos get spun and twirled in the air like they're being controlled by some sort of sorcery and not at the mercy of gravity. That's how good ChihHan Chao, 2015 Red Bull PAO champion, is at using the hand sticks to juggle these wild yo-yos. He's making the discs dance and tossing them back and forth with such flair that it's like they're floating orbs moving around him.
These colourful maps of Mars are the most accurate depiction of how gravity varies around the Red Planet. Created by measuring subtle variations in the gravitational field experienced by NASA spacecraft as they zip past the planet, the images allow us to understand what lurks inside better than ever.
I don't know what planet these guys are from but it's certainly not Earth because they don't follow the very simple laws of gravity and break the concept of balance and destroy the very idea of time. They can jump on and off a slackline like it's nothing and even do ridiculous tricks normal people couldn't pull off if they could fly.
Video: Zach Mueller has mastered the art of cardistry and in doing so probably destroyed the laws of gravity. The Fontaine cards he's using seem to have a mind of their own with special rules that don't apply to other objects on this planet. It's not so much that his hands are controlling the card but the card is controlling his hands. Cool trick!
Being in zero gravity has to be a never ending amount of fun. Everything that you boringly do in your normal life, all the things you don't bother to look twice at — they all become instantly more interesting because you have no idea what's going to happen. Just check this spinning T-handle in zero gravity, it spins one way and then reverses and spins the other way and then just goes crazy.
Can you imagine if you had a knob you can turn to sway gravity whichever way you like it? Clemen Wirth's imaginative experimental video, Gravity, just does that. Water can be poured upwards, paint can drip sideways, flying balloons can fly down and the whole world can be bent in any shape you want. It'd be such a cool superpower to have.
To this day, I've never felt dumber than when elementary school me thought that 100 pounds of bowling balls would fall faster than 100 pounds of feathers. I was a fool and I'll never forget it. This video doesn't show that riddle in action but something even cooler: how things fall at the same rate inside the world's largest vacuum chamber.
